What are the Speed Boost magic items in the game and what for?

The Speed Boost and Golden ratchet magic items help you to speed up the production of coins in service buildings. You can get these items in the following ways: - get one Speed Boost item from the Mages Tower once a day that goes to your Inventory and can be used from it; - buy them in the Store -> Magic (or use the button with the vessel depicted on it at the right side of the game window). NOTE: when you buy Golden ratchet magic item, it doesn't move to your Inventory but works immediately.
